Abstract: Systems and methods are described for providing maintaining state information during processing of data sets via execution of code on an on-demand code execution system. Rather than requiring that execution environments of such a system to maintain state, an intermediary device is disclosed which retrieves calls to the system from a call queue and iteratively submits the calls to the system. Each call within the queue corresponds to a data item of the data set to be analyzed. As calls are submitted to the system, the intermediary device submits state information within the call reflecting a state of processing the data set. A response to the call includes state information updated based on processing of a data item in the call. Thus, state information is maintained for processing the data set, without requiring persistence of state information within individual execution environments.

Abstract: Methods, system, and apparatuses may support end-to-end (E2E) quality of service (QoS) through the use of service layer (SL) sessions. For example, an application can communicate with a targeted device based on application specified schedule, latency, jitter, error rate, throughput, level of security, and cost requirements.

The method further includes initiating transmission of the object to the data consumer based on the servicing of the verification request.

Abstract: The techniques described herein enable a head-mounted display device to use a fiducial marker to identify an Internet of Things (IoT) device. The head-mounted display device can use the identifier to establish a network connection with the IoT device. For example, the identifier can include an Internet Protocol (IP) address, a Bluetooth address, a cloud IoT identifier (e.g., AZURE hub IoT identifier), or another type of an identifier. By using an electronic paper display, the IoT device can dynamically generate and display a new fiducial marker when a new identifier is assigned to the IoT device or is generated by the IoT device. Consequently, the head-mounted display device can detect the fiducial marker and extract the identifier for the IoT device from the fiducial marker so that the identifier can be used to establish a network connection with the IoT device.

Abstract: A method of generating a signature for a group of electronic messages that each include a plurality of characters comprises extracting a plurality of blocks of characters from each of the electronic messages, mathematically processing each of the blocks of characters from each electronic message, and generating a signature for the group of electronic messages based at least in part on the mathematically processed blocks of characters. In some embodiments a counting Bloom filter may be used to generate the signature. The signatures generated by these methods may be used to identify spam.

The system can include a memory device and a hardware processor. The memory device can store an application. The hardware processor can execute the application, characterize a user engagement with the application as being a first level of engagement or a second level of engagement, generate event data responsive to user interactions with the application, and control the batch collection of the event data depending on whether the user engagement with the application is characterized as the first level of engagement or the second level of engagement.

Abstract: Devices, methods, and program products are provided enabling Adaptive Bitrate (ABR) optimization upon initialization of a streaming video session. In embodiments, the method includes launching a streaming media interface application in response to user input. Substantially concurrently with application launch, the client media receiver further transmits a request over a communications network to a streaming media server for a sample video stream. As the video stream is received, the client media receiver plays the sample video stream as, for example, a background process. When subsequently receiving user input selecting streaming content for end user viewing, the client media receiver determines an optimized ABR setting based upon a recent ABR value of the sample video stream. The client media receiver transmits a request to the streaming media server for user-selected content stream at the optimized ABR setting and then presents the content stream for end user viewing.

Abstract: Techniques for transforming data based on a virtual topology are disclosed. A computer network is associated with a physical topology and a virtual topology. A physical topology is a particular arrangement of digital devices. A virtual topology is a description of a particular arrangement of virtual topology entities (VTEs). VTEs of the virtual topology are instantiated on digital devices of the physical topology. A processing component associated with a particular VTE processes data to perform one or more functions of the particular VTE. An emulation component associated with the particular VTE modifies the data to emulate performance of the functions by the particular VTE.

Abstract: A system may include a first processor for storing, in a key-value column-based database, data records from data sources of a cellular network that is transformed into a single format.

Each session record may include a velocity of an endpoint device associated with a session and a number of inter-cell handoff attempts for the session. Each session record may also be labeled with a session identifier comprising a customer identifier and a timestamp. The system may further include a third processor for creating cell-level records from the session records. Each cell-level record may include a plurality of key performance indicators for a cell site of the cellular network segregated by a plurality of endpoint device types.

Abstract: At least one set of enforceable policy provisions is identified within at least one defined service level policy to be enforced during runtime by a policy enforcement point (PEP). Each set of enforceable policy provisions includes a policy subject, a reference to a policy domain, and at least one assertion. Each identified set of enforceable policy provisions is transformed by the PEP into at least one runtime-executable processing rule that each includes at least one PEP processing action that each represents an atomic unit of policy enforcement level behavior executable by the PEP to enforce the respective at least one assertion against runtime objects associated with the policy subject within an area of runtime policy enforcement specified by the policy domain.

Abstract: In one embodiment, a network assurance service maintains a data lake of network telemetry data obtained by the service from any number of computer networks. The service generates a machine learning model for on-premise execution in a particular computer network to detect network issues in the particular network. To do so, the service repeatedly selects a candidate set of model settings based in part on the data lake of network telemetry data, trains a machine learning model using network telemetry data from the data lake that matches the candidate set of model settings, and tests performance of the trained model using an emulator that emulates network issues in the particular network. The service further deploys the generated machine learning model to the particular computer network for on-premise execution.

Abstract: Methods, systems, and devices are described for identifying images which may be of interest to a user based on their current geographic location. In some embodiments, a check is first performed to determine if the current geographic location is a location-of-interest. Images are searched that are in geographical proximity to the current geographic location of the user to identify images-of-interest. The images-of-interest may be designated in part based on actions taken by subjects having had interactions with the images. The user is notified based on the discovery of one or more images-of-interest. The one or more images-of-interest may be presented to the user through the use of map overlays and/or augmented reality techniques.

Abstract: At a stream management service, one or more storage servers of a first repository are assigned to store at least a first partition of a first data stream. At the first repository, records of different partitions are interleaved. In response to determining that a set of data records of the first partition meet a first criterion, a rearranged version of the set in which the data records of the first partition are contiguous is stored at a second repository. Using the rearranged version, one or more records of the first partition are provided to an application which meets a lag criterion.
